Some gemstones contain metals or toxins. Below is a list of the most commonly known toxic gemstones, but please be aware that this list is by no means complete. In fact, in this world, it would be difficult to find anything that doesn’t have some level of toxicity or if nothing else, an adverse reaction in the body. One can even die from drinking too much water. The best practice is the practice of common sense. Don’t drink too much water and don’t eat pounds of gemstone dust.
I do hope no one takes this to extremes. It isn’t as though licking a labradorite will land you in the hospital or anything. I’m also not suggesting one should suck on a crystal like it’s a tootsie pop either, obviously. Yes, there are some toxins in some gemstones and minerals but if you use common sense you will be fine. Most have to be heated or chemically treated to release toxicity. Some become toxic when inhaled in powder form such as when one is sawing or grinding the stone. The chances of dying or even getting sick from simply touching a gemstone and in most cases even putting one in your mouth for a hot second, are too slim to mention. Yes, be cautious. Please, don’t be paranoid and allow yourself to be distracted from the wonderful world of Crystals and Stones.
If you wish to make an elixir or essence from a known toxic gemstone, or you are unsure about a particular gemstone, only use the indirect method.
